LinuxQuestions.org - Entries for April 2016

Just annotations of little "how to's", so I know I can find how to do something I've already done when I need to do it again, in case I don't remember anymore, which is not unlikely. Hopefully they can be useful to others, but I can't guarantee that it will work, or that it won't even make things worse.

Like the common acceleration feature, but asymmetric. So you can reach the ends of the screen with whatever range of motion "feels right", even if it's actually "wrong".

You basically misappropriate this spreadsheet:

(Thanks to whomever came up with it!)

Perhaps drawing two rectangles one inside the other may help...

[MYSTERY SOLVED] What does "echo ???????????????" really do?

Posted 04-20-2016 at 08:39 PM by the dsc (linux-related notes)

It seems to alternate between listing an Nth file (somewhat obscurely related with the number of question marks) on the current folder, or giving some "history" entry, I guess.

That's weird.

Code:

22:54 **ROOT** /# echo ?
?
22:54 **ROOT** /# echo ??
??
22:54 **ROOT** /# echo ???
bin dev etc lib mnt opt run smb srv sys tmp usr var
22:55 **ROOT** /# echo ????
boot home proc root sbin
22:55 **ROOT** /# echo ?????

[WORK-AROUND] Bug on dragging windows of KDE/QT apps under openbox

If you accidentally (or not) click/hold and drag the left mouse button from the inner area ("client" or "any empty area") in a KDE/QT window, it starts to be dragged/moved along, but it's not dropped when you release the button, unlike the behavior with GTK windows (at least GTK2, I guess). You got to press "enter" or "esc", I guess.

Presumably that doesn't happen under KDE proper/kwin, maybe not even with other window managers, but I didn't...

Disable the annoying command-not-found handler on Ubuntu

Posted 04-04-2016 at 06:17 PM by the dsc (linux-related notes)

Add on .bashrc:

Code:

unset command_not_found_handle
alias cmdhelp=/usr/lib/command-not-found

So if it's just a typo there's no annoying mini-hang.

I'd rather have something like a "shopt -s safe-command-spell" thing than this, or at least as a first thing.

The alias is just in case you'd rather use for a command you thought you had installed. Sometimes the commands are under somewhat obscure package names, so it can...
